Abstract (en)

[origin: WO2009135779A1] The invention relates to a use of a multi-layer metal composite material, which is produced by way of roll-bonding and can be wound, in a vehicle structure, particularly a body structure. It is the object of the invention to provide a use of a metal composite material as an alternative to monolithic materials. The object is achieved in that the composite material is a lightweight composite material and comprises three layers of a steel alloy, wherein at least one of the layers is made of a steel alloy having higher strength or maximum strength.
